Follow along on the Hurricane and Severe Storm Sentinel (HS3) campaign. HS3 is a five-year mission specifically targeted to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. Read more
Earth’s temperature depends on how much sunlight the land, oceans, and atmosphere absorb, and how much heat the planet radiates back to space. This fact sheet describes the net flow of energy through different parts of the Earth system, and explains how the planetary energy budget stays in balance. Read more
On the 10th anniversary of the launch of NASA's Aura spacecraft, we offer 10 examples of how the satellite has changed our view of dust, pollution, aerosols, and ozone in our atmosphere. Read more
In the summer of 2014, scientists embarked on ship and aircraft expeditions between the U.S. East Coast and Bermuda in order to improve NASA's view of the oceans. Read more
Planes, balloons, and boots on the ground are just some of the approaches NASA scientists are taking this summer and fall in Alaska to investigate the region's changing landscapes, from forests and fire to ice and solar radiation. Read more
Industrialization has brought incredible societal advances and difficult pollution problems. From space, we can see skies clearing in some regions and darkening in others. The thin blue line of our atmosphere is still quite vulnerable. Read more
The United States has set aside nearly 84 million acres of historic and scenic land in its national parks system. In celebration of National Park Week, here are satellite views of ten of those national treasures. Read more
